HPLC-UV-NMR is a powerful technique for the identification and characterization of flavonoids. However, there are drawbacks, as NMR remains rather insensitive because of the need for solvent suppression, which has restricted the observable NMR range. Recently, two major research developments in HPLC-UV-NMR are post-column solid-phase extraction (HPLC-UV-SPE-NMR) and combination of HPLC-UV-SPE with capillary separations and NMR detection [89]. A post-column treatment of analyte focusing and multiple trapping through a SPE has solved the problem of sensitivity and solvent suppression. The separation and elucidation of three C-methylated flavanones and five dihydrochalcones from Myrica gale seeds have been achieved by HPLC-DAD-SPE-NMR and...

Traditional alkaloids have not been found, but spermidine amides have been isolated from the pollen of Myrica gale. In the tests reported here, Myrica asplenifolia gave a positive lest the following did not Comptonia peregrina, Myrica burmannii, M. califomica, M. cerifera, M. conifera, M. cordifolia, M. inodora, M. mexicana, M. oblongata, M. pilulifera, M. rubra, M. serrata, M. tomentosa. 

Anticancer activity was demonstrated in laboratory tests using extracts of leaves from a related species, Myrica gale, and a delphinidin (anthocyanin) extract showed anticancer and antiviral activity in test-tube experiments.
